Since you decided to go back and edit your post and bash me in it, please allow me retort.
Ok, so I went and did a little reading. Went back to school as it were. Methanol is CH3OH which means a Carbon molecule that has 3 hydrogen molecules attached to it is itself attached to an Oxygen...
Methanol is alcohol made mostly from natural gas afaik. Now if you can buy it in a form that contains an oil mixture like Nitro then I was unaware of that because I dont use it but you said 100% methanol which is just alcohol. Even if it is an alcohol/oil mix I'm not really sure I see a benefit...
This is complete overkill. Plus I wouldnt want to run my engines even for 30 seconds without any lubrication in there at all. You dont need to to do all of that to store a nitro engine. Even for long term storage just slather it up with ARO real good both in the glow plug hole and through the...
Heres the manual for that engine. It will have the stock settings in it.

The stock needle settings should be listed in the engines manual. What engine is it?
Idle needle should be set so that the carb has about a 1mm gap when fully closed.
I usually check my tank, fuel line by blowing through it while its under water but you dont necessarily have to do it under water. pinhole type leaks will be easier to indentify that way though.
If cleaning the carb doesn't work then Id test the fuel tank for air leaks as well as putting new fuel line on it. Make sure the exhaust pressure port isnt clogged up also and that the back pressure is pushing fuel through the system.
